Stopping of Deuterium in Warm Dense Deuterium from Ehrenfest Time-Dependent Density Functional Theory

Contributions to Plasma Physics

Magyar, Rudolph J.; Shulenburger, Luke N.; Baczewski, Andrew D.

In these proceedings, we show that time-dependent density functional theory is capable of stopping calculations at the extreme conditions of temperature and pressure seen in warm dense matter. The accuracy of the stopping curves tends to be up to about 20% lower than empirical models that are in use. However, TDDFT calculations are free from fitting parameters and assumptions about the model form of the dielectric function. This work allows the simulation of ion stopping in many materials that are difficult to study experimentally. (© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim).
